Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616062, here are decompositions:

3 + 31616059 = 31616062
29 + 31616033 = 31616062
41 + 31616021 = 31616062
53 + 31616009 = 31616062
83 + 31615979 = 31616062
89 + 31615973 = 31616062
479 + 31615583 = 31616062
659 + 31615403 = 31616062

Showing the first eight; more decompositions exist.
